The Imperial Guitar Company - Saginaw, Michigan

While searching for information on my The Imperial Co parlor guitar (that I now know for certain to have been made by the John Church Company in Cincinnati, Ohio) I stumbled across this very obscure manufacturer based out of Saginaw, Michigan.

Avery Block doesn't lead you anywhere on Google Maps so I had to dig deeper. I stumbled across a book written about Saginaw in 2009 which includes an old photograph of 'The Avery Building' and places it at the southeast corner of East Genesee Avenue and Jefferson Avenue. Unfortunately no buildings from the time period are still standing and the single building that remains was built in 1936.

Attempts to determine the identities of Holt and Mason were unsuccessful. They have fairly common last names and searching hundreds of census records that match is not worth the time. The company was missing from the 1899 edition of the book so its likely they did not survive into the 20th century.
